TECHNICAL FIELD

Various embodiment of the present disclosure relate to a radiant-heatsheet mounted on mobile communication terminal, and more particularly, amobile communication terminal provided with an antenna.

BACKGROUND

In general, a mobile communication terminal is provided with a batterypack within the body thereof to recharge and to use the battery pack. Inaddition, the mobile communication terminal includes a cover configuredto be detachably mounted on the rear side of the body of the mobilecommunication terminal so that after the cover is removed from themobile communication terminal, the battery pack mounted in the mobilecommunication terminal is separated and recharged using a charger. Therear side or cover of the mobile communication terminal is a portionwhich is directly in contact with a user's hand when the user grips themobile communication terminal. Thus, the user may feel heat generatedfrom the mobile communication terminal as it is.

Meanwhile, as the body of the mobile communication terminal is slimmedand a high specification Application Processor (AP) is used for themobile communication terminal, a problem of heat generation has beengradually encountered. A main board, on which various electroniccomponents are mounted, is a heat generation source of the mobilecommunication terminal. In particular, the AP mounted on the main boardis the main heat generation source.

In addition, it became possible for gradually popularized mobilecommunication terminals to conduct bidirectional local areacommunication in a contactless manner using a Near Field Communication(NFC) antenna in the mobile communication terminals. As compared withother types such as existing BLUETOOTH and ZIGBEE, the NFC antenna hasadvantages in that a communication setting time is short and lessmalfunctions in recognition although its data transmission speed isslow. As a result, the NFC antenna has been generally employed in mobilecommunication terminals and applied so that the NFC antenna is beingadvanced in various fields. Mobile communication terminals with NFCantennas are used as smart cards such as electronic money, electronicwallet, electronic ticketing, door key, and identification card andallow a user to share or exchange, for example, name cards, phonenumbers, photographs, or music with an acquaintance.

For ensuring smart functions, NFC antennas are mounted on predeterminedportions of mobile communication terminals. Considering mountability,the NFC antennas are usually mounted within the mobile communicationterminals, or on battery packs or battery covers of the mobilecommunication terminals.

SUMMARY

As the bodies of mobile communication terminals have been slimmed and ahigh specification Application Processor (AP) has been used for themobile communication terminal, the problem of heat generation hasgradually increased. In addition, upon analyzing a heat generation partof the mobile communication terminal using a thermo-graphic camera, itcan be seen that a wide variation in temperature occurs at a boundarybetween a main board part and a battery pack part. It can be verifiedthat the main board region of the mobile communication terminalgenerates a lot of heat and the battery pack is relatively cold.

Accordingly, it is necessary to transfer the heat toward the batterypack region. However, when an NFC antenna is mounted within a batterypack, it may be difficult to apply, for example, a radiant-heat sheetfor transferring the heat to the inside of the battery cover since theperformance of the NFC antenna may be degraded. Due to this, theradiant-heat sheet is applied to a region other than the battery regionso that there may be a limit in dissipating the heat.

Consequently, when the radiant-heat sheet is applied, it isconventionally important to widen the area of the radiant-heat sheet asmuch as possible in order to dissipate the heat. However, due to thedegradation of the performance of the NFC antenna, there may be adifficulty in widening the radiant-heat sheet.

To address the above-discussed deficiencies, it is a primary object tosecure and apply a radiant-heat sheet as wide as possible so that heatgeneration of the mobile communication terminal can be reduced withoutdegrading performance of an antenna mounted within a mobilecommunication terminal or on an attachable/detachable battery pack.

In addition, various embodiments of the present disclosure reduce heatgeneration of a mobile communication terminal by transferring heat froma heat generation part to an area where no antenna is disposed using aradiant-heat connection part.

In order to solve the problems described above, there is provided amobile communication terminal according to an aspect of the presentdisclosure. The mobile communication terminal includes: a displaymodule; a rear cover; an inner support structure positioned between thedisplay module and the rear cover and including a first surface facingthe display module and a second surface facing a side opposite to thedisplay module; a first radiant-heat sheet positioned between the firstsurface of the support structure and the display module; a printedcircuit board positioned between the first radiant-heat sheet and thefirst surface of the support structure; and a second radiant-heat sheetpositioned between the second surface of the support structure and therear cover.

According to another aspect of the present disclosure, there is provideda protective cover of a mobile communication terminal. The protectivecover includes: a first cover that covers a first surface of the mobilecommunication terminal; and a second cover connected with the firstcover and configured to be provided on the second surface of the mobilecommunication terminal to cover a battery accommodation space of themobile communication battery when the protective cover is assembled onthe mobile communication terminal.

The radiant-heat part includes a radiant-heatconnection part that transfers heat from the heat generation sourcetoward a region which is not provided with an antenna and is relativelycold compared to the heat generation source.

According to yet another aspect of the present disclosure, there isprovided a battery cover for a mobile communication terminal includingan antenna. The battery cover includes: a radiant-heat part provided onone surface of the battery cover, and disposed not to be superposed onthe antenna and a radiant-heat connection part extending from theradiant-heat part. The radiant-heat radiates heat transferred from themobile communication terminal to a first region which is relativelycold, and the radiant-heat connection part radiates heat transferredfrom the mobile communication terminal to a second region positioned ina direction which is different from that of the first region.

According to yet another aspect of the present disclosure, there isprovided a battery pack attachable to and detachable from a mobilecommunication terminal.

Whenthe mobile communication terminal 10 is configured to include aremovable, battery pack (namely, a battery pack capable of beingattached and detached from the mobile communication terminal 10), therear side of the mobile communication terminal 10 includes anattachable/detachable battery cover 15.

The mobile communication terminal described below is configured toinclude an removable (attachable/detachable) battery pack, and a batterycover assembled to be removable from the mobile communication terminal.Hereinafter, configurations of a radiant-heat antenna device, a coverhaving the same, a battery pack, and a mobile communication terminalaccording to various embodiments of the present disclosure will bedescribed.

FIG. 3 is a perspective view illustrating a mobile communicationterminal according to an embodiment of the present disclosure in adisassembled state in which the mobile communication terminal isprovided with a radiant-heat sheet. Referring to FIG. 3, the mobilecommunication terminal (hereinafter, referred to as a “terminal”)according to the present embodiment includes a display module 1000disposed on the front side of the terminal, and a rear cover 1100disposed on the rear side of the terminal, and also includes a PrintedCircuit Board (PCB) on which various electronic components are mounted,an inner support structure 1200, and one or more radiant-heat sheets1400 and 1500 between the display module 1000 and the rear cover 1100.

The inner support structure 1200 includes a first surface 1220 facingthe display module 1000 and a second surface 1210 facing the sideopposite to, namely facing away from, the display module 1000. The firstsurface 1220 is the rear side of the inner support structure, and thesecond surface 1210 is the front side of the inner support structure.The inner support structure 1200 is a kind of a rear case that can be abasic frame that supports various mounted electronic components. Theinner support structure 1200 includes one or more metal patterns 1513and 1610, and a space that accommodates a component including at leastone metal pattern. The at least one metal pattern included within theinner support structure 1200 can be configured in an antenna pattern andthe component can be a battery pack 1600. The metal pattern can beprovided on the battery pack 1600, and the battery pack 1600 includesthe metal pattern 1610 on one side thereof. The metal pattern 1610 canbe an NFC antenna.

The inner support structure 1200 further includes an inner bracket 1300that supports the PCB and various electronic components. The PCB can bedisposed between the inner support structure 1200 and the inner bracket1300. The inner support structure 1200, the PCB, and the inner bracket1300 are assembled in a vertically stacked structure and can supportvarious electronic components. The inner support structure 1200, theinner bracket 1300, and the PCB include openings 1215, 1310 and 1315,respectively, to locate the battery pack 1600 therein.

The one or more radiant-heat sheets include first and secondradiant-heat sheets 1400 and 1500. The first radiant-heat sheet 1400 isdisposed between the display module 1000 and the first surface 1220 ofthe inner support structure and can be configured in a shape to transferthe heat transferred from a heat generation source to a relatively coldregion. For example, an AP or an LED disposed on the PCB may beconsidered a heat generation source in the terminal, and in particular,the AP may be considered the hottest heat generation source.

In addition, at least a part of the second radiant-heat sheet 1500 canbe positioned between the second surface 1210 of the inner supportstructure and the rear cover 1100. The second radiant-heat sheet 1500 isattached to or housed in the rear cover 1100, in which the secondradiant-heat sheet 1500 is disposed to not be superposed on the metalpattern 1610. The second radiant-heat sheet 1500 includes a firstportion 1510 at a position corresponding to the heat generation body, inwhich the first portion 1510 extends from the second radiant-heat sheetat least not to be superposed on the position corresponding to the metalpattern 1610. The extending second portion 1520 transfers the heattransferred from heat generation body to a component, for example, oneside of the battery pack 1600 where the metal pattern 1610 is notprovided.

At least one of the first radiant-heat sheet 1400 and the secondradiant-heat sheet 1500 includes one or more of natural graphiteparticles, compressed particles of exfoliated graphite, artificialgraphite particles, copper, graphene particles, carbon nanotubes (CNT),and graphene hybrid.

In the following description of the mobile communication terminalincluding the radiant-heat sheets according to various embodiments ofthe present disclosure, the mobile communication terminal will bedescribed in comparison to a second mobile communication terminalincluding a radiant-heat sheet for the convenience of description.

FIG. 18 is a table representing temperature distributions of the mobilecommunication terminals to which radiant-heat sheets are attachedaccording to various embodiments. FIG. 18 is a test table representingtemperatures and temperature distributions after heat generationsources, such as APS, are disposed on left regions of the mobilecommunication terminal (see FIG. 3a), and radiant-heat sheets of variousshapes are attached to the inner surfaces of the battery coversremovably assembled on the mobile communication terminals.

It can be seen that the temperature of the heat generation source is thehighest (52.1° C.) when no radiant-heat sheet is attached to the batterycover (No sheet). In addition, it can be seen that in the case whereradiant-heat sheets are attached to the battery covers (Case #1 to Case#4), the temperature of the heat generation part (rear side temperature)is the lowest (47.8° C.) when the heat of the heat generation source istransferred to the battery pack using the radiant-heat connection part(Case #3).

Hereinafter, descriptions will be made on the mobile communicationterminal radiating heat according to various embodiment of the presentdisclosure with reference to FIG. 18 as well.

FIGS. 4A and 4B are a front view and a rear view of a mobilecommunication terminal (hereinafter, referred to as “terminal”) having anear field wireless communication antenna mounted therein according tothe prior art, wherein FIG. 4A illustrates a mobile communicationterminal in a state where a battery cover is removed and a battery packis mounted and FIG. 4B illustrates an inner surface of the removedbattery cover. FIG. 5 is a cross-sectional view of a mobilecommunication terminal having a near field wireless communicationantenna mounted therein according to the prior art

As illustrated in FIGS. 4A and 4B and FIG. 5, when the mobilecommunication terminal 30 is configured such that a battery pack 31 isremovable, a battery cover 32, which is attachable to and detachablefrom the rear side of the body of the terminal, can be configured. Forthe convenience of description, an attachment/detachment structure ofthe battery cover 32 is omitted. Although not illustrated, theabove-mentioned attachment/detachment structure of the battery cover 32is configured by a combination of a plurality of protrusions and aplurality of recesses.

As illustrated in FIG. 4A, when the battery cover 32 is removed from theterminal 30, the mounted state of the battery pack 31 is shown. Thebattery pack 31 is seated in a battery slot provided on an inner surface300 of the terminal and electrically connected to a battery connector 36to supply electric power. On a left region of the battery pack 31, aheat generation source 34, such as an AP mounted on a main board (notillustrated) (mounted inside the rear side of the terminal to bestacked) is positioned, and on a region above the battery pack 31, acamera c, an LED provided in a flash f, and a socket s are positioned.An example of the heat generation source 34 can be, for example, the AP34, the LED f, or the camera c element, but the AP 34 can be consideredthe hottest heat generation source within the terminal. Accordingly, theplace where the AP 34 exists may be considered a hot spot that is thehottest region in the terminal 30.

Specifically, with reference to the center of the terminal 30, the heatgeneration source 34 is positioned substantially in the left region, thebattery pack 31 is positioned in the right region to be spaced apartfrom the heat generation source 34, and the camera c, the LED of theflash f and the socket s are positioned in the upper region. The heatgeneration source 34 is positioned in the left region of the terminal 30at a position adjacent to the battery connector 36. Since the heatgeneration source 34 should be positioned in the left region to beadjacent to the camera c, the flash f and the battery connector 36 inorder to facilitate interlock there between and power supply, the heatgeneration part 34 is disposed on the main board preferably at aposition adjacent to the battery connector 36. In addition, the camerac, the flash f, and the card socket s are preferably disposed not to befar from the heat generation source 34.

The antenna 33 and the radiant-heat part 35 can be configured to providethe antenna function to the terminal. When the antenna 33 is an NFCantenna, the NFC antenna 33 can be provided at a predetermined positionon the top surface 310 of the battery pack 31. When the NFC antenna 33is provided on the battery pack 31, the NFC antenna 33 can be disposedat a place adjacent to the heat generation part 34. That is, when thebattery pack 31 is roughly divided into an upper region and a lowerregion, the NFC antenna 33 can be mounted on the upper region of thebattery pack 31.

A radiant-heat part 35 is mounted on an inner surface 320 of the batterycover 32, which is a surface facing the inner surface 300 of theterminal 30 when the battery cover 32 is assembled with the terminal, soas to reduce the temperature of the heat generation part 34. When thebattery cover 32 is assembled on face the inner surface 300 of theterminal 30, the radiant-heat part 35 is disposed to be superposed onthe heat generation source 34 so that heat is radiated in a directionaway from the heat generation source 34 by the radiant-heat part 35.Thus, the temperature of the heat generation source 34 can be reduced,and the temperature of the terminal can be entirely reduced. Meanwhile,since the radiant-heat part 35 includes a metallic material, which isexcellent in heat conductivity, for example, copper (Cu), theradiant-heat part 35 is disposed to not be superposed on the antenna 33.

When the radiant-heat part 35 is disposed to be superposed on theantenna 33, the performance of the antenna 33 may deteriorate. When thetemperature of the heat generation source 34, for example, the AP,increases, the main function of the terminal may deteriorate so that theperformance of the terminal may be degraded. Further reduction of thetemperature of the heat generation source 34 is required. As theterminal 30 is further improved in specification in the future, the heatgeneration problem of the AP will become further evident and theperformance of the mobile communication terminal may be affected. InFIG. 4B, reference numeral “321” denotes a camera opening, referencenumeral “322” denotes a flash opening, and reference numeral “g” denotesa battery attachment/detachment recess.

Hereinafter, configurations of an antenna, a battery pack having thesame, and a mobile communication terminal according to variousembodiment of the present disclosure will be described with reference tothe accompanying drawings.

FIGS. 6A and 6B are a front view and a plan view of a mobilecommunication terminal having a near field wireless communicationantenna mounted therein according to various embodiments of the presentdisclosure, wherein FIG. 6A illustrates a mobile communication terminalin a state where a battery cover is removed and a battery pack ismounted and FIG. 6B illustrates an inner surface of the removed batterycover. FIG. 7 is a cross-sectional view schematically illustrating amobile communication terminal having a near field wireless communicationantenna mounted therein according to various embodiments of the presentdisclosure.

As illustrated in FIGS. 6B and 6A and FIG. 7, the battery pack 41 isseated in a battery slot provided on an inner surface 400 of theterminal 40 and electrically connected to a battery connector 46 tosupply electric power. In a left region of the battery pack 41, a heatgeneration source 44, such as an AP, mounted on a main board B(illustrated in FIG. 7) is positioned, and in a region above the batterypack 41, a camera c, an LED provided in a flash f, and a socket s arepositioned. The heat generation source 44 can be, for example, the AP,the LED, or the camera c element, but the AP can be considered therelatively hottest heat generation source within the terminal.Accordingly, the place where the AP exists can be considered a hot spotthat is the hottest region in the terminal.

With reference to the center of the terminal body 40, the heatgeneration source 44 is positioned substantially in the left region, thebattery pack 41 is positioned in the right region to be spaced apartfrom the heat generation source 44, and the camera c, the LED and thecard socket are positioned in the upper region. The heat generationsource 44 is positioned in the left region of the terminal body 40 at aposition adjacent to the battery connector 46. Since the heat generationsource 44 should be positioned in the left region to be adjacent to thecamera c, the flash f and the battery connector 46 in order tofacilitate interlock there between and power supply, it is preferablethat the heat generation source 44 is disposed at a location adjacent toelectronic components which consume a lot of power, if possible.

In addition, the antenna 43 and the radiant-heat part 45 is configuredto provide an antenna function to the mobile communication terminal 40.The antenna 43 mounted on the mobile communication terminal 40 can be athin and flexible NFC antenna or a wireless charging antenna. When theantenna 43 is the NFC antenna, the NFC antenna may be or may not beprovided on the top surface of the battery pack 41. When the NFC antenna43 is not provided on the battery pack 41, the NFC antenna 43 can beprovided on a predetermined region of the rear side 400 of the terminalbody 40.

According to an embodiment, when the NFC antenna 43 is provided on thebattery pack 41, the NFC antenna 43 is disposed at a location that isfar from the heat generation part 44. That is, when the battery pack 41is roughly divided into a first region (lower region), and a secondregion (upper region 410), the NFC antenna 43 is disposed in the lowerregion of the battery pack 41. The first region is positioned arelatively long distance from the heat generation source 44 compared tothe second region, and the second region is positioned a relativelyshort distance from the heat generation source 44 compared to the firstregion. The antenna 43 is disposed in a protrusion of the first regionand further includes a connection antenna 430 to be connected with thebattery connector 46.

As illustrated in FIG. 6B, a radiant-heat part 45 is attached to theinner surface of the battery cover 42 so as to reduce the temperature ofthe heat generation part 44. When the battery cover 42 is assembled onthe terminal body 40, the radiant-heat part 45 is disposed to besuperposed on the heat generation source 44 so that heat is radiated ina direction far away from the heat generation source 44 by theradiant-heat part 45. Thus, the temperature of the heat generationsource 44 can be reduced and the temperature of the terminal body 40 canbe entirely reduced. Since the radiant-heat part 45 includes a metallicmaterial that is excellent in heat conductivity, for example, copper,the radiant-heat part includes a radiant-heat connection part 450 whichis disposed not to be superposed on the antenna 43 and transfers heat toa region which is relatively cold as compared to the heat generationsource 44. An example of the cold region can be a region 420 that is notsuperposed on the connection antenna 430 in the second region of thebattery pack 41. That is, the radiant-heat connection part 450 absorbsheat transferred from the heat generation source 44 and radiates theheat to the region 420 of the battery pack, which is relatively cold.The radiant-heat connection part 450 can be configured in a sheet shapeusing a material that is the same as that of the radiant-heat part 45.The radiant-heat part 45 and the radiant-heat connection part 450include one or more of natural graphite particles, compressed particlesof exfoliated graphite, artificial graphite particles, copper, grapheneparticles, CNT, and a graphene hybrid. The radiant-heat part and theradiant-heat connection part to be described later can include theabove-mentioned materials.

As described below, the radiant-heat connection part 450 provides aneffect of reducing the temperature of the heat generation source 44. Ascan be seen from FIG. 18, the temperature of the rear surface of theheat generation source is reduced greatest.

The first region is the lowerregion. The second region refers to a battery region where the NFCantenna 43 is not disposed. The second region is the upper region. Thesecond region includes one or more connection antennas 430 so as toelectrically connect the NFC antenna 43 to a battery connector. Theconnection antenna 430 extends from the antenna 43 toward abattery-protective circuit board 414 (see FIG. 9). An end of theconnection antenna 430 is connected to the battery-protective circuitboard 414, and electrically connected to the battery connector 46 (seeFIG. 6) by the battery-protective circuit board 414. Thebattery-protective circuit board 414 connected with the connectionantenna 430 is protected by being enclosed by a battery-protectivecircuit board cap 412. The connection antenna 430 is not superposed onthe radiant-heat connection part 450 so as not to affect degradation ofan antenna performance. The connection antenna 430 can be configured invarious shapes and patterns. The connection antenna 430 illustrated inFIG. 8 extends substantially linearly in the longitudinal direction inthe periphery of the battery pack 43 to be electrically connected to thebattery-protective circuit board 414. Without being limited to theshape, however, the connection antenna 430 can be configured in variousshapes as long as it is connectable to the battery connector. Of course,when the shape of the connection antenna 430 changes, the shape of theradiant-heat connection part may also change.

FIGS. 10A and 10B are front view and a plan view of a mobilecommunication terminal having a near field wireless communicationantenna mounted therein according to various embodiments of the presentdisclosure, wherein FIG. 10A illustrates a mobile communication terminal50 in a state in which a battery cover is removed and a battery pack ismounted and FIG. 10b illustrates an inner surface of the removed batterycover 52. FIG. 11 is a perspective view illustrating a battery packhaving a near field wireless communication antenna mounted thereinaccording to various embodiments of the present disclosure. Indescribing a radiant-heat NFC antenna according to an embodiment of thepresent disclosure with reference to FIGS. 10A and 10B and FIG. 11,descriptions on the redundant components compared to the radiant-heatNFC antenna illustrated in FIGS. 8 and 9 will be omitted. Since theradiant-heat NFC antenna illustrated in FIGS. 10A and 10B and FIG. 11has the same configuration as that illustrated in FIGS. 8 and 9, exceptfor the connection antennas 530 and 531 and the radiant-heat connectionpart 550, the mobile communication terminal of the present embodimentwill be described mainly with the connection antennas and theradiant-heat connection part.

The connection antenna extending from the antenna 53 mounted on thefirst region (lower region) of the battery pack 51 extends across thesecond region 510 in the horizontal and vertical directions to beconnected to the battery connector 56. The connection antenna extendsalong the periphery of the second region 510 finally toward the batteryconnector 56, in which the connection antenna includes a horizontalconnection antenna 530 and a vertical connection antenna 531.

The end of the vertical connectionantenna 531 is connected to the battery-protective circuit board (seeFIG. 9) to be electrically connected to the battery connector 56.

The radiant-heat part 55 includes a radiant-heat connection part 550that is not superposed on the antenna 530 and the connection antenna 531which are mounted in the second region. The radiant-heat connection part550 extends from the radiant-heat part 55 in the vertical direction totransfer the heat transferred from the heat generation source 54 to aregion 510 where the antenna mounted on the battery pack and theconnection antenna are not mounted. That is, the radiant-heat connectionpart 550 absorbs the heat from the heat generation source 54, andradiates the heat to the region 510 of the battery pack. The size of theradiant-heat connection part is slightly smaller than the radiant-heatconnection part illustrated in FIG. 6. This is due to the connectionantenna. Consequently, the radiant-heat connection part 550 absorbs theheat transferred from the heat generation source 54 and transfers theheat to the relatively cold region 510 where the connection antenna isnot disposed on the battery pack, thereby lowering the temperature ofthe heat generation source 54.

The radiant-heat part 65 includes a radiant-heat connection part 650that is not superposed on the antenna 63 and the first connectionantenna 630. The radiant-heat connection part 650 extends in thevertical direction from the radiant-heat part 65 to transfer heattransferred from the heat generation source 64 to a region 610 where theantenna mounted on the battery pack and the connection antenna are notmounted. That is, the radiant-heat connection part 650 absorbs the heatfrom the heat generation source 64 and transfer the heat to the region610 of the battery pack. Consequently, the radiant-heat connection part650 absorbs the heat transferred from the heat generation source 64 andtransfer the heat to the relatively cold region 610 where the connectionantenna of the battery pack is not disposed, thereby lowering thetemperature of the heat generation source 64.

FIGS. 14A and 14B are a front view and a plan view of a mobilecommunication terminal having a near field wireless communicationantenna mounted therein according to various embodiments of the presentdisclosure, wherein FIG. 14A illustrates a mobile communication terminalin a state in which a battery cover is removed and a battery pack ismounted and FIG. 14B illustrates an inner surface of the removed batterycover.

The battery pack 71 includes a top surface 711, a bottom surface 712,and a plurality of side surfaces 713 with reference to the stateillustrated in FIG. 15. As already described, an NFC antenna 73 ismounted in the lower region of the top surface of the battery pack 711.The NFC antenna 73 can be provided with a plurality of connectionantennas so as to connect the NFC antenna 73 to a battery connector 76.The connection antenna according to the present embodiment includes afirst connection antenna 730 disposed on the top surface 711 of thebattery pack, a second connection antenna 731 disposed on one sidesurface 713, and third connection antenna 732 disposed on the bottomsurface 712.

The radiant-heat part 75 includes a radiant-heat connection part 750that is not superposed on the antenna 73 and the first connectionantenna 730. The radiant-heat connection part 750 extends in thevertical direction from the radiant-heat part 75 to transfer heattransferred from the heat generation source 74 to a region 710 where theantenna mounted on the battery pack and the connection antenna are notmounted. That is, the radiant-heat connection part 750 absorbs the heatfrom the heat generation source 74 and transfers the heat to the region710 of the battery pack. Consequently, the radiant-heat connection part750 absorbs the heat transferred from the heat generation source 74 andtransfers the heat to the relatively cold region 710 where theconnection antenna of the battery pack is not disposed, thereby loweringthe temperature of the heat generation source 74.

FIGS. 16A and 16B are a front view and a rear view of a mobilecommunication terminal having a near field wireless communicationantenna mounted therein according to the prior art, wherein FIG. 16Aillustrates a mobile communication terminal in a state where a batterycover is removed and a battery pack is mounted and FIG. 16B illustratesan inner surface of the removed battery cover.

As illustrated in FIG. 16A, when the battery cover 82 is removed fromthe terminal body 80, the mounted state of the battery pack 81 is seen.The battery pack 81 is seated in a battery slot provided on the innersurface 800 of the terminal body to be electrically connected to thebattery connector 86, thereby supplying power. In the region above thebattery pack 81, a heat generation source 84 mounted on the main board(not illustrated) (mounted to be stacked in the rear side of theterminal), for example, AP, is positioned, and in the upper region ofthe battery pack 81, a camera c, and an LED provided on a flash f.Although the heat generation source 84 can be, for example, the AP 84 orthe LED of the flash f, the AP 84 may be considered the relativelyhottest heat generation source within the terminal body. Accordingly,the place where the AP 84 exists in the terminal 80 may be considered ahot spot as the hottest region.

Specifically, approximately with reference to the center of the terminalbody 80, the heat generation source 84 is positioned in the upper regionand the battery pack 81 is positioned in the lower region to be spacedapart from the heat generation source 84. The heat generation source 84can be positioned at a place adjacent to the battery connector 86approximately at the center of the upper region of the terminal body 80.The heat generation source 84 should be positioned adjacent to thecamera c, the flash for the battery connector 86 in the upper region foreasy interlocking there between or easy power supply. Thus, the heatgeneration source 84 is preferably disposed at a place close to thebattery connector 86 on the main board, if possible. In addition, it isdesirable that the camera c and the flash f are also disposed at a placethat is not far from the heat generation source 84.

Meanwhile, the antenna 83 and the radiant-heat part 85 can be configuredto provide an antenna function to the terminal. When the antenna 83 isan NFC antenna, the NFC antenna 83 is provided at a predeterminedposition on the top surface of the battery pack 81. When the NFC antenna83 is provided on the battery pack 81, the NFC antenna 83 is mounted ata place adjacent to the heat generation part 84. Then, the NFC antenna83 can be positioned in the center of the rear side of the terminal 80.The NFC antenna 83 is positioned in the center in consideration of theuser's convenience in using the terminal 80.

A radiant-heat part 85 can be mounted on an inner surface 820 of thebattery cover 82 (the surface facing the rear side 800 of the terminalwhen the battery cover 82 is assembled with the terminal) in order toreduce the temperature of the heat generation part 84. When the batterycover 82 is assembled to face the rear side 800, the radiant-heat part85 is disposed to be superposed on the heat generation source 84 so thatheat is radiated by the radiant-heat part 85 in a direction far awayfrom the heat generation source 84, thereby reducing the temperature ofheat generation source 84, and hence the temperature of the entireterminal. Meanwhile, since the radiant-heat part 85 includes a metallicmaterial that is excellent in heat conductivity, for example, copper(Cu), the radiant-heat part 85 is disposed not to be superposed on theantenna 83. When the radiant-heat part 85 is disposed to be superposedon the antenna 83, the performance of the antenna 83 deteriorates. Theheat generation problem of the terminal body 80 leads to a lot of userdiscontent and thus it is necessary to further reduce the temperature ofthe heat generation source 84. However, there is a limit in enlargingthe area of the radiant-heat part 85 attached to the battery cover 82.As the terminal 80 is improved to have higher specifications in thefuture, the heat generation problem of the AP will be further magnified,and may severely affect the performance of the mobile communicationterminal.

FIGS. 17A and 17B are a front view and a plan view of a mobilecommunication terminal having a near field wireless communicationantenna mounted therein according to various embodiments of the presentdisclosure, wherein FIG. 17A illustrates a mobile communication terminalin a state where a battery cover is removed and a battery pack ismounted and FIG. 17B illustrates an inner surface of the removed batterycover.

As illustrated in FIGS. 17A and 17B, the battery pack 91 is seated in abattery slot provided on the rear side of the terminal body to beelectrically connected to the battery connector 96, thereby supplyingpower to the terminal. In the region above the battery pack 91, a heatgeneration source 94 mounted on the main board B (see FIG. 6), forexample, AP, is positioned, and in the upper region of the battery pack91, a camera c, and an LED provided on a flash f. Although the heatgeneration source 94 can be, for example, the AP, the LED, or a cameradevice, the AP is the relatively hottest heat generation source withinthe terminal body and may be considered the heat generation source.Accordingly, the place where the AP exists in a mobile communicationterminal 90 may be considered a hot spot in the hottest region.

With reference to the center of the terminal body 90, the heatgeneration source 94 is positioned in the upper region and the batterypack 91 is positioned in the lower region to be spaced apart from theheat generation source 94. In the upper region, for example, the camerac, the LED or a card socket can also be provided. The heat generationsource 94 can be positioned at a place adjacent to the battery connector96 in the upper region of the terminal body. The heat generation source94 should be positioned adjacent to the camera c, the flash for thebattery connector 96 in the upper region for easy interlocking therebetween or easy power supply. Thus, the heat generation source 94 isdisposed at a place preferably close to the battery connector 96 on themain board, if possible.

In addition, the antenna 93 and the radiant-heat part 95 can beconfigured to provide an antenna function to the mobile communicationterminal 90. When the antenna 93 mounted on the mobile communicationterminal 90 can be an NFC antenna that is thin and is made of a softmaterial, or a wirelessly charged antenna. When the antenna 93 is theNFC antenna, the NFC antenna may be or may not be provided on the topsurface of the battery pack 91. When the NFC antenna 93 is not providedon the battery pack 91, the NFC antenna 93 can be provided in apredetermined region of the rear side 900 of the terminal body 90.

According to the present embodiment, when the NFC antenna 93 is providedon the battery pack 91, the NFC antenna 93 can be disposed at a placewhich is far from the heat generation source 94. That is, when themounting area of the battery pack 91 is roughly divided into a firstregion and a second region, the NFC antenna 93 is disposed in the firstregion. The first region can be positioned a relatively long distancefrom the heat generation source 94 compared to the second region, andthe second region can be positioned a relatively short distance from theheat generation source 94 compared to the first region. The antenna 93is disposed in the first region and further includes a connectionantenna 930 to be connected to the battery connector 96.

As illustrated in FIG. 17b, a radiant-heat part 95 can be mounted on aninner surface of the battery cover 920 in order to reduce thetemperature of the heat generation part 94. When the battery cover 92 isassembled on the terminal body 90, the radiant-heat part 95 is disposedto be superposed on the heat generation source 94 so that heat isradiated by the radiant-heat part 95 in a direction far away from theheat generation source 94, thereby reducing the temperature of heatgeneration source 94, and hence the temperature of the entire terminalbody 90. Meanwhile, since the radiant-heat part 95 includes a metallicmaterial that is excellent in heat conductivity, for example, copper(Cu), the radiant-heat part 95 is disposed not to be superposed on theantenna 93 and includes a radiant-heat connection part 950 thattransfers the heat to a relatively cold region compared to the heatgeneration source 94. An example of the cold region can be the region910 where the battery pack 91 is not superimposed with the connectionantenna 950. That is, the radiant-heat connection part 950 absorbs theheat transferred from the heat generation source 94 and radiates theheat to the relatively cold region 910 of the battery pack. Theradiant-heat connection part 950 is formed in a sheet shape using thesame material as the radiant-heat part 95. The radiant-heat part 95 andthe radiant-heat connection part 950 include a graphite material. Thetemperature of the heat generation source 94 is further reduced by theradiant-heat connection part 950.
